PORT JERVIS — Some weekend train service on the Port Jervis line will be replaced with busing for the next month to accommodate bridge repairs near Tuxedo.

The busing will start this week, after the evening rush hour Friday, and end before the morning rush hour Monday. The same workaround will be in place on the weekends of July 31-Aug. 2, Aug. 8-10 and Aug. 15-17.

The interim schedule will permit Metro-North crews to replace 160 track timbers on two bridges that carry the Port Jervis line over the Ramapo River.

The work will cost $125,000 in labor and materials — and another $90,000 for busing.

NJ Transit, which operates the Port Jervis line for Metro-North, said the 9:58 p.m. Friday train and 12:40 a.m. Saturday train from Hoboken, N.J., will terminate at Suffern. Customers who are traveling beyond Suffern will transfer to buses at Ramsey/Route 17, and then customers traveling beyond Harriman will transfer from buses to trains at Harriman.

On Saturdays and Sundays, trains will operate from Port Jervis to Harriman, where customers will transfer to buses to Ramsey/Route 17 and then trains to Hoboken.

Customers boarding at Tuxedo and Sloatsburg will be bused to Ramsey/Route 17.

Some inbound Port Jervis line trains will be canceled between Suffern and Hoboken. Customers will finish their trips on NJ Transit trains that will operate up to 60 minutes later and should be aware that all trains could be held for bus connections.

Every effort will be made to maintain connections at Secaucus, N.J., to Pennsylvania Station, officials said.

Outbound trains on Saturdays and Sundays will operate between Hoboken and Suffern, with switches to buses at Ramsey/Route 17, and trains at Harriman.

Again, some trains will be canceled and/or delayed as long as 75 minutes.

Regular service will resume Mondays with the 12:40 a.m. train from Hoboken. Additional details are posted at njtransit.com.
